IMPROVED EVAPORATOR OF MEXICO, OHIO.

FOR SACCHARINE Juices.

Speriiication forming part of Letters Paieni No. 34.72?, dated March 25, 18! 2.

To all whom z't may concern/.-

Be it known that I, ABRAHAM BARE, ot' Mexico, in the county of Wyandot and State of Ohio, have invented certain new and useful Improvements in Pans for Evaporating Saccharine Juices; and I do hereby declare that the following is a description thereof in terms which I1 now .think sufficiently full, clear, and exact, reference being had to the annexed drawings, making apart of this specification, in which- Figure lis a top view Fig. 2, a vertical section through the line w x of Fig. l; Fig. 3, a cross-section through the line y y of Figs. 1 and 2, and Fig. 4 a cross-section through the line z z of the same iigures.

The nature of my invention consists, mainly, in a double pan, the under part of which is used for water and steam, while the sirup is above, in combination with the pan generally in use, whereby I am enabled to evaporate thick Or thin sirup free from dangerof burning, and with any degree of heat desired, and at any desired point.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The rst pan, A, is placed directly over the iire-arch B, and is provided with a series of bars, a, which prevent the passage of the scum while all the juice i'lows through the openings b below the bars. A spout, c, at the corner enables me, when desirable, to clean the pan by a flow of water through it. Another spout, d, having a gate, e, at its inner end, admits the passage ofthe juice, clarified, into the strainer f, which is made removable, so that it may be cleaned at any time, and thence into the second pan, G, the first part or section, g, of which is directly over and iirmly combined with the pan containing the water or steam-generator D, and which steam-generator and iirst section of second pan are both also directly over the iire-grates E. Directly opposite the first section ofthe second pan the iirc isv conducted into the chimney F, as seen at h; and between the chimney and arch4 and steam-generator, and directly over the iiue 71 is placed aheater, G, into which cold water is fed, from which it passes through tubei into the steam-generator hot or warm, as desired, to supply the wants of the generator. A tube, 7c, passes through the arch from the bottom ofthe generator, and at the opposite side from the heatam enabled to discharge the water from the second or middle section, on, of the second pan is the steam-chamber H, into which the steaml passes from the generator through openings n n in the top of the division or partition I, between the generator and steam-chamber, and so high above the water in the generator as to prevent any flow into the chamber. The -steam is also admitted at the sides of the pan 0 o by allowing the partition `I in the lower pan at each side to extend up higher than its center, so that openings may be made in the side above the water in the generator, and on each side of said partition, between the generator and chamber, as seen at p p, Fig. et. As soon as the water begins to boil in the gen erator the steam escapes freely into the steamchamber, and is there retained, as desired, or allowed to escape through the valve or tube q on the same side with the chimney, or is carried forward, if desired, to evaporate still further under the third section, r, in the secdischarge-tube of the second evaporating-pan, which slide also allows steam to escape in last pan; or it may be retained under the middle pan in the chamber, and the sirup drawn orf at the spoutz discharging from that section. Nhen finished, the sirup is drawn off from either the second or third sections of the second pan, which may be extended, still farther, but it is never drawnoff until after it reaches the section of evaporator over the strainer like that shown at J; or strainer J there and placed on tube t. The end of the bottom K of the second pan from the fire is left open to allow condensed steam to pass off.

is as follows: rlhe juice is iirst boiled by the direct heat of the fire in the first pan, and there clarified. It then passes, as described, over the steam-generator, where the evaporation continues by the boiling of the water dier, by which means, on raising the gate Z, I

steam -generator when desired. Beneath thev ond pan by drawing out the slide s near the quantities, as desired, to be used under the" steam-chamber, and is then passed through a may be removed from tube a when not needed The operation of my improved evaporatorl rator, the steam is allowed to pass through the valve s and out at the end. The cooling-sections may be still further increased in number so as to obtain any temperature desired.

Having thus described my invention vand shown the manner in which it operates, what I claim therein, and desire to secure by Letters Patent of the United States, is-

l. So constructing pans for evaporating sacv charine juices as that in the first stages of evaporation it is done by the agency of iire alone,rand in the second stages by steam, first closely confined and Very hot, then in apartments less heated, the desired effect is attained.

2.' That particular construction of evaporators wherein the same fire which evaporates in the rst stages generates at the saine time the steam for the second stages of evaporation.

3. The double pan, constructed as described, the iirst lower section of which contains the generator, the second the steam-chamber, and the third and additional sections for gradually decreasing the temperature, for the purposes set forth.

4. The slide or Valve between the steamchamber and the last section below, in combination with the doublepan, substantially as and for the purpose described.

5. The heater or supply-pan for water, arranged as described, in combination with the generator, for the purpose set forth.

6. The rst pan, constructed as described,-

in combination with the second pan, when its separate sections are heated by different degrees of heat, for the purpose set forthl In witness whereof I have hereunto set my hand this 10th `day of February, 1862.
